SLIIDING-WINDOVY MECHANISM.

Application filed August 26, 1920.

T 0 all whom it may concern f Be it lrnown that l, ELncIn l). FARUM, acitizen of the United States, and a resident of Ualrland, county ofAlameda, and State of California, have invented a new and usefulVSliding-Window Mechanism, of which the following is a specification.

My invention relates to slidingV window mechanism and particularly tomeans for preventing the rattle of the slidable windows such as are usedon automobile tops.

An object of the inventionv is to provide simplerand effective means forpreventing the rattle of windows, which will be automatically placed inoperative position or released therefrom by the movement of the sash.

Another object of the invention is to provide means of the characterdescribed which may be thrown into operative position or releasedtherefrom at a point intermediate the eXtreme forward or rearwardposition of the sash by merely moving the latter in one direction or theother.

The invention possesses other objects and features of advantage, some ofwhich, with the foregoing, will be set forth in the followingdescription of the preferred form of my invention which is illustratedin the drawings accompanying and forming part of the specification. ltis understood that l do not limit myself to the showing made by the saiddrawings and description., as I may adopt variations ofthe preferredform within the scope of my invention as set forth in the claims.

Referring to said drawings:

Figure 1 is aver-tical section of the top of an automobile equipped withslidable windows and the mechanism of my invention. Parts of the insidelining of the top are shown broken away in order toV disclose theconstruction more clearly.

Figure 2 is a longitudinal sectionof one side of the top, the plane ofsection being indicated by the line 2 2 of Fig. 1.

Figure 3 is a vertical section of one side of the top taken on the line3 8 of Fig. 1.

Figure 4 is a side view vof one of the members of the clampingmechanism.

Briefly expressed the mechanism as here shown comprises a window framein which is arranged a set of sashes supported therein by hangers whichslidably engage a perforated track.l Clamping mechanism is arsenal No.406,172.

ranged on the track and moves with but is normally released from clampedengagement with the sash. Vilhen, however, during the movement of thesash the proper open` ing or perforation in the track is encountered bythe clamping mechanism, a part of the latter is permitted to passthrough the opening and engage the sash. Thereafter a slight continuedmovement of the sash will operate to force the clamping mechanism intotight engagement therewith, thereby causing the mechanism and thehangers to be pressed against opposed surfaces of the track with aconsiderable force. To effect the release of the sash it is onlynecessary to slide it in the reverse direction. By providing a number ofopenings in the track the sash may be clamped in several intermediatepositions. Means are also provided for enabling the clamping mechanismto pass over the intermediate openings should it be desirable to merelyclamp the sash at one or the other of its extreme end positions.

A detailed description of the present embodiment of the inventionfollows:

The mechanism of my invention. as has been hereinbefore mentioned, isparticularly adapted for use in connection with the slidable windows ofautomobiles and accordingly have shown such an embodiment in thedrawings. The body 2 of the automobile here illustrated is of theenclosed type and is formed with the usual top 3 having` a permanentside window t between which and the windshield is the opening 5. Thesides of the opening 5 are in the form. of a frame 7 which includespockets 8 and 9 and in which is slidably disposed a pair of `sashes 11and 12. The pocket 8 is formed between the permanent window 4 and theinside wall 13 of the top and serves to enclose the sashes 11 and 12when Vthey are in their rearward or open position. The pocket 9 isformed between the inner and outer walls 13 and 11iat the top of theopening 5 and extends practically the full length thereof. Fixed in thepockets 8 and 9 and spaced from the outer and inner walls thereof is atrack 16 formed on itsopposite sides with grooves 17 and 18 in whichengage hangers 19 and 21respectively4 that support the sashes 11 and 12.The sash 11 is arranged `to move forward the full length of the opening5 so that it may close the forward half thereof, whereas the sash 12 isarranged to their extreme end positions as well as at an intermediateposition, which will permit the clamping or releasing of the sash,whether at the end or intermediate position by the continued or reversemovement of the sash. F iXed to each sash forlongitndinal movementtherewith but slidable transversely thereof is a clamping member 29preferably disposed between. the hangers and arranged in the grooves ofthe track. ln the present embodiment of the invention part of thenecessary transverse movement of the clamping .member is permitted byforming' it of aresllient material but it is obvious that such movementmay be permitted by mounting- 1t 'yielding'ly Formed inthe lower face3() of both grooves 17 and lSfof the track are a plurality oflongitudinally spaced openings 3l in which may enten. so Vas to eifectthe clampingof the sash in a manner which will be hereinafter described,one of a pair of arms 32 that is pivoted to the member29.

The arms are preferably pressed by a spring 33 vso that the free endsthereof vwhich are provided with anti-friction rollers 34 will normallybear against the faces 30. T he arm 35 which is pivoted to theclampingmember associated with the sash ll is ada-pted to engage eitherthe openings 37 or 38 thereby allowing the sash il to be clamped in itseXtreme forward position or intermediate position respectively. Theother arm 39 of this set is adapted to engage the-opening 41 so that thesash ll may loe-clamped in its extreme rear position. ln a practicallysimilar manner the arms 42 and 43 of the member 29 associated with thesash v12 are adapted 'to engage the openings44 and 45 respectively andthereby clamp the sash l2 in its eXtreme forward and rearward positionrespectively. By arranging the arms einaffe such an ooenin' whereas thearm' i b Z1 which follows will readily pass over it. In accordance withthe ,foregoing as clearly seen inrFigure l, the sides of the openings37, 38 and 44are sloped downwardly and forw'ardly Awhereas Vthe sides ofopenings 4lV slope downwardlyand rearwardly. The operation' of themechanism is as follows: Assuming' that it is desired to move the sashl1 from a rear position to the position shown in Figure l, the sash ismoved forward so that the arm 35 on reaching the opening B8 enters itand comes in contact with the top of the sash. When the arm firstcontacts with the sash top it is forced to assumeA a positionin whichits longitudinal axis lies substantially parallel to the sides of theopenng. This isdue to thefact thatthe upper surface of the clampingmember is already in contact with the upper face 47 of the track grooveand thereby prevents the arm from becoming fully extended. However-'uponthe vcontinued movement of the sash the arm abuts against the forwardside of the opening and causes the clamping' member to flex suiiicientlyto Venable the free end of the arm to lie back of a vertical lineintersecting its pivotal point-'in which position the clampingmechanismislocked. To release the sash from its clamped engagement with thetrackit is merely necessary to move the sash in the reversedirectionthus causinpthe arm' and clamping'mem'ber to go through theprevious movements in the reverse order.

The top of the sash at the point where the rollers of the arms engage isprovided with a plurality of plates 48, one or more of which maybe addedor removed should 4it be de'- sired to vary the tension with which thesash is clamped to the frame.

trance of the arms in the intermediate opening 38 when it is desired t'oclamp the sash in its extreme forward position. As Vhere shownthe saidmeans comprises a plate 49 which is slidably mounted in the lower wallof the track. Vso that it can be moved to close the top of the openingand therebypreventV the entrance f the roller, as the arm during themovement of the sash, passes over the opening. The plate 49 is providedwith a handle 5l which is disposed to one side f 'the path of thesashll.

While I have 'shown but, one intermediate opening 38 it,is' bvious thatthe number can be increased in accordance with the number ofintermediate psitions it may' be desired. to clamp the sashes;
